Product Summary

The NCN4555MNR2G is a level shifter analog circuit designed to translate the voltages between a SIM Card and an external microcontroller or MPU. A built−in LDO−type DC−DC converter makes the NCN4555MNR2G useable to drive 1.8 V and 3.0 V SIM card. The device fulfills the ISO7816−3 smart card interface standard as well as GSM 11.11 and related (11.12 and 11.18) and 3G mobile requirements (IMT−2000/3G TS 31.101). The NCN4555MNR2G typical applications are (1)SIM Card Interface Circuit for 2G, 2.5G and 3G Mobile Phones; (2)Identification Module; (3)Smart Card Readers; (4)Wireless PC Cards.
